Answer:
That day 51 child tikets were sold
Step-by-step explanation:
To do this problem we have to make 2 equations, one that represents the number of entries and the other that represents the money
x = child tickets
y = adult tickets
x + y = 132
x * $5.20 + y * $9.00 = $994.20
First we have to solve for the x in the first equation
x + y = 132
x = 132 - y
Now we replace the x with (132 - y) in the second equation
x * $5.20 + y * $9.00 = $994.20
(132 - y) * 5.20 + y * 9.00 = 994.20
686.4 - 5.2y + 9y = 994.2
-5.2y + 9y = 994.2 - 686.4
3.8y = 307.8
y = 307.8/3.8
y = 81
We replace y with its value in the first equation
x = 132 - y
x = 132 - 81
x = 51

Answer:
9cm
Step-by-step explanation:
The formula for the area of a parallelogram is base x height.
You have the height, 7cm, and the area, 63cm^{2}[/tex].
So the equation is B x 7 = 63. Simply take 63 divided by 7 and you get 9.
Answer: 9cm
The sum of the degrees for all triangles is 180, so just add the two you have and subtract from 180.
1. 58 + 47 = 105
180 - 105 = 75
Therefore x = 75
2. 91 + 26 = ?
180 - ? = ?
etc
